Use of Synthetics in Vortec Engines
I just purchased a new '06 Chevrolet Trailblazer with double digit miles. I want to use Mobil 1 fully synthetic in the inline 6-cylinder for the life of the vehicle, but was told at the dealership not to use synthetic in the Vortec engines - that I should only use conventional oil. Any input on fully synthetic vs. Chevy Vortec engines?

We do not know of any reason why Mobil 1 fully synthetic oil cannot be used in your 2006 Chevrolet Trailblazer.
